数据加密标准

不错的希尔代码，希尔是一种经典的加密算法，加密可以通过一线形变换，脱密再做依次逆变换。密钥就是变换矩阵本身。-good code Hill, Hill is a classic encryption algorithms, encryption can transform line shape, followed again from close inverse transform. Key is the transformation matrix itself.

Twofish 采用128位数据块(128 bits lock)，128-192-256-bit 可变长度密钥。-using Twofish 128 blocks of data (128 bits lock) EliteConnect (TM) Universal-192-256-bit variable-length keys.

从一个随机文件读取256字节数据形成数据区DArea，再应用洗牌法所给的方法生成0~255的一个全排列DTab。试分别写出"求DArea中全部数据经 （1）以DTab为S-盒； （2）以DTab为P置换 -from a random file read 256 byte data area DArea form data, re-shuffling in law application to the formation of 0 ~ 255 DTab a full array. Try to write were "seeking DArea by which all data (1) DTab S-boxes; (2) DTab replacement for the P

把AES算法封装成DLL方便掉用。 我只是做了简单修改，版权归原作者所有-put into AES Packaging swap used to facilitate DLL. I just made a simple change Lastings all the original author

sha加密算法实现，经过FPGA验证的！-sha encryption algorithm, after FPGA validation!

这是一个加密程序，可对字符串进行加密，字符串和密钥的内容和长度可以设置。-This is an encryption program that encrypt the string, string and key content and length can be set.

MD消息摘要程序，MD5以512位分组来处理输入的信息，且每一分组又被划分为16个32位子分组，经过了一系列的处理后，算法的输出由四个32位分组组成，将这四个32位分组级联后将生成一个128位散列值。-MD news summary procedures, MD5 to 512 groups to deal with the importation of information and each group was divided into 16 groups of 32 seats, after a series of processing, the output from the algorithm four groups composed of 32, these four sub-32 will generate a cascade 128 the hash value.
